Verdict
The clearest difference is ads: AUX B at none against OCO's shown. AUX B also leads on review sentiment (89% vs 73%) and rating (4.8 vs 4.6). OCO's advantage is update cadence (every 5 weeks vs every 4 months) and ratings volume (2.4K vs 293). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. AUX B sells 2 one-off in-app purchases and OCO sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
AUX B holds the better App Store score, 4.8 against 4.6.
